SPECIFICATION forming part of Letters Patent No. 681,628, dated August 27, 1901.

Application filed January 21, 1901. erial No. 44,055. (No model.) I

To ct-ZZ whom it may concern.-

Be it known that I, GEORGE J. OUZNER, a citizen of the United States, residing at Miamisburg, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Spinning-Machines, of which the following is a specification.

My invention relates to an improvement in spinning-machines, the object being to simplify the mechanism, to cheapen the cost, and to increase the efficiency.

In the spinning-machine of the old art employing a rotary flier, a capstan thereon, and a receiving-bobbin, each taking motion from a separate driving device, it is obvious that a discrepancy in the feed of any one or more of these separate drives throws out of balance or proper time movement the operations of the remaining parts. For instance, lost action, belt-slippage, or an overspeeding of the capstan, will produce an over or an under twisting of the string for which no compensation is made in the other parts, and consequently the function of both the flier and bobbin would be deranged. The preferred form of my invention entirely obviates all these difficulties,and the parts may be adapted to be readily applied to an ordinary spinner.

The features of my invention will be more fully set forth in the description of the accompanying drawings, forming a part of this specification, in which- Figure 1 is a sectional elevation of myimprovement. Fig. 2 is a side elevation of my improvement. Fig. 3 is a front plan view of the revolving friction-disk. Fig. 4 is a plan view of the stationary friction-plate.

A represents the ordinary flier journaled on the ordinary frame.

B represents the central spindle passing through the head 2 of the flier. Journaled upon this spindle is the bobbin 0, fixed to the bobbin-sleeve O, which passes through the head 2 of the flier.

D represents a gear-sleeve journaled on the bobbin-sleeve outside of the head 2 of the flier and attached thereto for driving the flier. To this sleeve is cast or otherwise fixed the driving-gear D.

E represents a bearing device suitably based upon the machine-frame, in which the outer end of the gear-sleeve D is journaled. One face of this bearing device is formed into a friction-disk E, which will be later described. (See Fig. 4..)

Turning to the other head 1 of the flier F represents a funnel-shaped tube upon which this head of the flier is journaled, the funnel portion of the tube opening toward the fiberfeeding mechanism. (Not necessary to be shown.) To this journal-tube, just inside of the capstan-head 1, is fixed a gear 3. The capstan has the usual grooved rollers G H fixed to the gears 4 5, respectively, which are journaled on the fiier'head 1, with the said gearwheels 4 5 respectively inter-meshed with the intermediate fixed gear 3, from which they are driven when the flier is rotated.

The brake mechanism for the bobbin-sleeve consists of the following parts.

Secured to the friction-disk E is a smaller disk I, by means of truss-rods a b 0. These form the stationary heads between which the rotary friction-disk J is adjustably secured. This friction-disk J is feathered and splined to the bobbin-sleeve, so as to turn therewith and so as to allow the bobbin-sleeve to be reciprocated therein.

01 represents a friction-washer of suitable material interposed between the stationary 8e and rotary friction-disks.

K represents a coil-spring, one end of which bears against an adjusting-collar L, screwthreaded into the disk I. The other end of said spring bears against the rotary frictiondisk J, pressing it normally into contact with the opposingfriction-disk. Itwill beseen that by means of this adjusting-collar the degree of friction can be most delicately adjusted, and hence the tension between the flier and 0 bobbin can thus be positively controlled.

h h represent aerating-tubes through the face of the rotary disk to supply air to the contacting frictional surfaces. The outer ends of the tubes are preferably funnel-shaped, 5 by means of which air-currents are created by the revolution of the disk and constantly supplied to the frictional surfaces. It is obvious that in the high speeded mechanism such as above described a means for keep- I00 ing the temperature approximately down to great practical value.

safety is of The stationary disk E has orifices M to supply air to the Contacting frictional surfaces.

The mechanism for reciprocating the bobbin is of usual form (shown in Fig. 2) consisting of the collar M, arm N, worm-shaft O, and gears a: y z, worm-shaft Q, and the gears 'v at the end of said worm-shaft Q.

Mode of operation: The driving means is shown, preferably, in the form ofa gear,which may be positively driven by a counter-shaft in the lower part of the machine-frame. It

is obvious that a belt-pulley might be em ployed in lieu thereof, or other equivalent power-transmitting devices may be employed.

As the flier is turned by this gear to whichit.

and the bobbin are both independently journaled within the flier and receive their speed therefrom, so that the relative movements of these separate parts are invariable. The

- capstan can operate on the string no faster and no slower than it is fed by the flier, and

the speed of the bobbin is likewise in a direct and invariable ratio to the speed of the flier. The advantages of this invention may be partially realized by independently driving the capstan as well as the flier and leaving the bobbin independently jonrnaled, though it is obvious that a single drive is the simplest as well as the best. In short, by means of a single drive the highest possible efficiency of the spinning-machine is realized, because of the invariable relative speed of the several parts.

It is obvious that in addition to the simplicity,construction, and operation of spinhing-machines by my invention, owing to the perfect and invariable performance of the representative functions of the several parts, the quantity of the output is greatly increased; but of even more importance is the improved character of the result in quality. It is evident that in the old spinning-machines even the slightest variation,not enough to actually break the twine, causes an unevenness and non-uniformity of string which greatly damages its commercial Value and utility. With my invention an unbroken string of practical uniformity in texture and quality is produced.

Having described my invention, I claim- 1. In a fiber-spinning machine, a revolving flier, means for driving the same, a capstan jonrnaled on the flier, power-transmitting devices between the capstan and flier, an independently-jonrnaled bobbin-shaft, a brake mechanism for said shaft, and means for reciprocating said shaft, whereby the relative rotations of the flier, capstan and bobbinshaft are maintained invariable, substantially as specified.

2. In a spinning-machine, a flier provided with two heads, a bobbin-shaftindependently jonrnaled in one of said heads, means for retarding the rotation of said shaft, means for reciprocating said shaft, a capstan j onrnaled on the other flier-head, power-transmitting devices between said flier and capstan, and a single driving mechanism, substantially as specified.

3. In a spinning-machine, a flier provided with two heads, a driving device attached to one of said heads, a bobbin-shaft independently jonrnaled in one of said heads, a retarding mechanism for said shaft, a funnelshaped receiver upon which the other head of the flier is jonrnaled, a capstan jonrnaled inside of said head, and power-transmitting devices between said flier and capstan, substantially as specified.

4. In a spinning-machine, a brake mechan- .ism for the bobbin-shaft consisting of two stationary disks trussed together on said shaft, one being a friction-disk, a rotary disk fixed to turn with said shaft between said stationary disks, a spring interposed between one of said stationary disks and the rotary disk, adapted to force the rotary disk normally against the stationary friction disk, and means for adjusting the tension of said spring, substantially as specified.

5. In a spinning-machine, a brake mechanism for the bobbin-shaft consisting of two stationary disks trussed together on said shaft, a disk fixed to turn with and slide on said shaft between said stationary disks, a spring interposed between the rotary disk and one of said stationary disks, a sleeve screw-threaded into the stationary disk against which the spring abuts, adapted to regulate the tension, substantially as specified.

6. In a spinning-machine, in combination with a brake mechanism for the bobbin-shaft, a stationary disk and a rotary disk normally in contact therewith, and aerating ducts formed through the rotary disk adapted to conduct currents of air upon the contacting frictional surfaces when in motion, substantially as specified.

In testimony whereof I have hereunto set my hand.
